Before You Begin
PLEASE READ THIS BEFORE USING.
The following basic safety precautions should always be taken.
1. Close supervision is necessary when the device is used by, on, or near children,
handicapped persons or invalids.
2. Use the device only for the intended use described in this User Guide.
3. Do not use test strips and control solutions which are not supplied by the
manufacturer.
4. Do not use the device if it is not working properly, or if it has suffered any damage.
5. Before using any product to test your blood glucose, read all instructions
thoroughly and practice the test. Do all quality control checks as directed and
consult with a diabetes healthcare professional.
6. KEEP THIS USER GUIDE WITH YOU.
Intended Use
The system is intended for use outside the body (
in vitro
diagnostic use only).
It should be used only for testing blood glucose (blood sugar) and only with fresh
capillary whole blood samples. The system is intended for use in the home and in
clinical settings. It should not be used for the diagnosis of diabetes or for the testing of
newborns.
Getting To Know Your System
The OKmeter Direct Blood Glucose Monitoring System.
The OKmeter Direct system uses the latest technology to provide you with easy and
comfortable testing. The system requires only a 0.7 μL of blood sample to complete
the testing in only 6 seconds.
The OKmeter Direct system consists of
1. OKmeter Direct Blood Glucose Meter
2. OKmeter Direct Blood Glucose Test Strips
Principle of Measurement
Blood glucose is measured by an electrical current that is produced when a blood
samples mixes with the reagent (special chemicals) of the test strip. The electrical
current changes with the amount of glucose in the blood sample. The OKmeter Direct
meter measures the strength of the electrical current, calculates your blood glucose
level and then displays your result in either milligrams of glucose per deciliter (mg/dL) or
millimoles of glucose per liter (mmol/L).
Caution
1. The user should not take any decision of medical relevance without first consulting
his or her medical practitioner.
2. Call your doctor immediately if you experience symptoms that are not consistent with
your blood glucose test results.
3. High altitudes above than 3,402 meter (11,161 ft) may affect the test results.
4. Temperatures outside the range of 10°C to 40°C (50°F to 104°F) may affect the test
results. Do not test beyond of temperature range.
IMPORTANT HEALTH-RELATED INFORMATION
1. Apply only capillary whole blood sample to test your blood glucose. Applying other
substances or plasma, serum will cause wrong results.
2. Severe dehydration and excessive water loss may cause false low results. If
you believe you are suffering from severe dehydration, consult your healthcare
professional immediately.
3. Test results below 60 mg/dL (3.3 mmol/L)*1 indicates low blood glucose
(hypoglycemia). Test results greater than 240 mg/dL (13.3 mmol/L)*2 indicates high
blood glucose (hyperglycemia).If your results are below 60 mg/dL (3.3 mmol/L) or
above 240 mg/dL (13.3 mmol/L), repeat the test, and if the results are still below 60
mg/dL (3.3 mmol/L) or above 240 mg/dL (13.3 mmol/L), consult your healthcare
professional immediately.
4. Inaccurate results may occur in severely hypotensive individuals or patients
in shock. Inaccurate low results may occur for individuals experiencing a
hyperglycemic-hyperosmolar state, with or without ketosis. Critically ill patients
should not be tested with blood glucose meters.
5. Abnormal red blood cell counts (hematocrit level below 20% or above 60%) may
cause false results. Please consult your healthcare professional if you do not know
your hematocrit level.
6. Interference: Reducing substances occurring in the blood naturally (uric acid,
bilirubin) or from therapeutic treatments (ascorbic acid, acetaminophen) will not
significantly affect OKmeter Direct test results. However, elevated concentrations
of these substances may affect test results. The compounds listed in the tables
were found to have no affect at the concentration indicated.

REPLACING THE BATTERY
The OKmeter Direct meter comes with TWO 1.5V AAA alkaline batteries.
Battery life will vary depending on usage, so always keep spare batteries on hand.
The battery should last about 1000 tests or 12 months when testing 3 times a day.
When the batteries symbol appears on the meter display, battery is getting low. You will
still be able to test with low battery, but you should replace them as soon as possible.
When battery symbol and E-b shows up in the meter display, the meter will no longer
give results and you must replace the batteries immediately. Please always have spare
batteries with you to ensure that you can replace the battery anytime.
SETTING TIME AND DATE

IMPORTANT :
1.The time, date and unit of measurement can ONLY be changed in the setting mode. Therefore,
when you perform a blood glucose testing, it is not possible to change those parameters.
2.Your meter displays test results in milligram per deciliter (mg/dL) or millimoles of glucose per
deciliter. Use of the wrong unit of measure may cause you to misinterpret your blood glucose
level, and may lead to incorrect treatment. Please always consult with your healthcare
professionals before you reset the unit of measure.
3.While the meter is in the setting mode, if no button is pressed for 1 minute, the meter will turn off
automatically.
Prepare For Blood Sampling
Adjustable Lancing Device
Your lancing device and lancets are used for obtaining
capillary blood samples from the puncture site.
Lancet
Setting your Lancing Device
